DEEP-WELL PUMP.

Specification of Letters Patent.

Patented Feb. 11, 1919.

Application filed. February 19, 1918. Serial No. 218,167.

To all whom it may concern:

Be it known that I, NORMAN O. FLEMING, a citizen of the United States,residing at Huntington Park, in the county of Los Angeles and State ofCalifornia, have invented a new and useful Improvement in Deep- WellPumps, of which the following is a specification.

My invention relates to the art of pumping water, and more particularlyto pumps which are adapted to handle considerable quantities of waterfrom medium or considerable depths. The invention resides in the novelcombination and association of parts as set forth in the accompanyingdescription and shown on the annexed draw- 111 s.

Tn these drawings, which are for illustrative purposes only,

Figure 1 is a side elevation partly in section of one embodiment of myinvention.

Fig. 2 is a front view partly in section on a plane represented by theline 2-2 of Fig. 1.

Fig. 3 is a front elevation of the pump with the buckets at one extremeposition, all parts behind a plane represented by the line 33 of Fig. 1being omitted for the sake of clearness.

Fig. 4 is a similar view of the pump with the buckets in their otherextreme position.

Fig. 5 is a detail of a link.

Fig. 6 is a detail of a guide takeup.

In the form of my invention illustrated in these drawings, a frame 11 isemployed,

this frame being composed of two lower members 12 and two upper members13 held together with spacing rods 14. Turning freely in journals 15 isa countershaft 16 which carries a belt wheel 17 at one end and a pinion18 at the other. The pinion 18 meshes with a gear 20 which is secured toone end of a three-crank-pin-twobearing crankshaft 21. The crankshaft 21turns freely in journals 22 secured to the frame 11.

Pivoted on each of the two outer crank pins is a lower connecting rod 23and pivoted on the center crank pin is an upper connecting rod 24. Thelower rods 23 are pivoted on a lower wrist pin 25 carried in a lowerbeam 26 which is in turn free to turn on a pin 27. The upper rod 24 ispivoted on a wrist pin 28 carried in an upper beam 29 pivoted on a pin30. The pins 27 and 30 Each of the beams 26 and 29 carries at its outerend a link pin 31 on which one end of a link 32 is pivoted, the otherend of said link being pivoted on a crosshead pin 33 carried in an uppercrosshead 34 or a lower crosshead 35.

Each of the crossheads 34 and 35 consists of a body 36 in which the pin33 is secured and a pair of guide plates 37 which are secured to thebody 36 by bolts 38 and which straddle vertical guides 39 carried in aframe 40. The frame 40 is bolted or other wise rigidly secured to theframe 11. The pins 31 project outside the beams 26 and 29 and areprovided with an external thread on which beam guides 41 are threaded,these beam guides each having a set screw so placed as to engage thepins 31 and prevent guides 41 from turning on the pins 31, as shown inFig. 6. The proportions of the parts is such that the pins 31 at allpoints in their stroke are inside and between the guides 39. The beamguides are adjusted on the pins 31 so that they engage but slide freelybetween the guides 39, it being possible to adjust the beam guides 41 atany time to take up any wear thereon or on the guides 39. By using thebeam guides 41 and so placing them that they engage the guides 39, theouter end of the beams 26 are guided to take care of any side strainsthereon.

Threaded in the body 36 of the upper crosshead 34 is an inner rod 50,this rod passing through a stuffing box 51 in the lower body 36 to whichan outer rod 52 is secured. The rods 50 and 52 pass downwardly into thewell through a discharge T 53 secured to the top of the pump column 54.

The frame 11 is mounted on a base 60, being secured thereto by means ofbolts 61. Formed on the lower members 12 are housings 62 in which rollerblocks 63 are placed, these roller blocks sliding up and down and beingactuated by screws 64. Turning freely in a cavity 65 in the bottom ofeach block 63 is a roller 66, this roller providing a ready means forsliding the frame 11 over on the base when the bolts 61 are removed andthe screws 64 are used to force the blocks 65 down.

The method of operation is as follows:

Power being applied to the shaft 16 by means of a belt, not shown, onthe belt wheel 17, the shaft 16 turns the shaft 21 through the pinion 18and the gear 20 which are of any practical desired ratio to suit thepump speed and the speed of the driving means.

The rotation of the crank shaft 21 drives the beams 26 and 29 throughthe rods 23 and Qt, the beams moving from the position shown in fulllines in Fig. l to the position shown in dotted lines in that figure.This movement of the beams 26 and 29 reciprocates the crossheads 3i andand reciprocates the rods 50 and 52. The rods 50 and 52 are in turnconnected to suitable buckets, not shown, in a pump barrel, also notshown, in accordance with standard practice in duplex two bucket pumps.

What I claim is l. A duplex deep well pump comprising a frame; upper andlower beams located in the same plane; pins on which said beams arepivoted; said pins being parallel to each other and secured in saidframe; a crank shaft having three crank pins, said crank shaft beinglocated between said beams and journaled in said frame; means fordriving said crank shaft; a pair of connecting rods each journaled atone end on one of the outer crank pins of said crank shaft; a wrist pinsecured in one of said beams on which the other end of both of said pairof connecting rods is journaled; a single con- Gopies of this patent maybe obtained for necting rod journaled on the center crank pin of saidcrank shaft; a wrist pin secured in the other of said beams on whichsaid single connecting rod is j ournaled; and linkages for connectingthe free end of each of said beams with the buckets of the pump.

:2; A pump as in claim 1 also comprising vertical guides secured to saidframe between which the free ends of said beams travel; and takeup meanson said free ends forengaging said guides.

3. A pump as in claim 2 in which eachof said takeup means comprises apump rod pin secured in the free end of one of said.

beams and projecting outwardly at either side of saidfbeam saidprojecting ends being threaded; beam guides threaded on said projectingends; and means for preventing said guides from turning on said pin.

4:. A pump as in claim 3 in which said linkages each comprisea crossheadengaging but sliding freely on said vertical guides; and a link pivotedat one end on said pump rod pin and at the other end on a pin carried insaid crosshead.

In testimony whereof, I have hereunto set my hand at Los Angeles,California, this five cents each, by addressing the Commissioner oflatents, Washington, I). G.
